Chapter 2. Adjusting and using your monitor

This section will give you information on adjusting and using your monitor.

Comfort and accessibility

Good ergonomic practice is important to get the most from your personal computer and to

avoid discomfort. Arrange your workplace and the equipment you use to suit your individual

needs and the kind of work that you perform. In addition, use healthy work habits to maximize

your performance and comfort while using your computer. For more detailed information on

any of these topics, visit the Healthy Computing Web site at:

http://www.lenovo.com/healthycomputing/.

Arranging your work area

Use a work surface of appropriate height and available working area to allow you to work in

comfort.

Organize your work area to match the way you use materials and equipment. Keep your work

area clean and clear for the materials that you typically use and place the items that you use

most frequently, such as the computer mouse or telephone, within the easiest reach.

Equipment layout and setup play a large role in your working posture. The following topics

describe how to optimize equipment setup to achieve and maintain good working posture.

Positioning your monitor

Position and adjust your computer monitor for comfortable viewing by considering the

following items:

• Recommended viewing distance between the eye and the monitor screen is 1.5 x the

diagonal of the screen. Solutions in meeting this required distance in cramped office

situations include pulling desk away from wall or divider to make room for monitor, using

flat panel or compact displays placing the monitor in the desk corner, or placing the

keyboard in an adjustable drawer to create a deeper working surface.

• Monitor height: Position the monitor so your head and neck are in a comfortable and

neutral (vertical, or upright) position. If your monitor does not have height adjustments,

you might have to place books or other sturdy objects under the base of the monitor to

achieve the desired height. A general guideline is to position the monitor such that the top

of the screen is at or slightly below your eye-height when you are comfortably seated.

However, be sure to optimize your monitor height so the line of site between your eyes

and the center the monitor suits your preferences for visual distance and comfortable

viewing when your eye muscles are in a relaxed state.

• Tilt: Adjust the tilt of your monitor to optimize the appearance of the screen content and to

accommodate your preferred head and neck posture.

• General location: Position your monitor to avoid glare or reflections on the screen from

overhead lighting or nearby windows.

Chapter 2. 2-2

The following are some other tips for comfortable viewing of your monitor:

• Use adequate lighting for the type of work you are performing.

• Use the monitor brightness, contrast controls, if equipped to optimize the image on your

screen to meet your visual preferences.

• Keep your monitor screen clean so you can focus on the screen’s contents.

Any concentrated and sustained visual activity can be tiring for your eyes. Be sure to

periodically look away from your monitor screen and focus on a far object to allow your eye

muscles to relax. If you have questions on eye fatigue or visual discomfort, consult a vision

care specialist for advice.

Quick tips for healthy work habits

The following information is a summary of some important factors to consider to help you

remain comfortable and productive while you use your computer.

• Good posture starts with equipment setup: The layout of your work area and the setup of

your computer equipment have a large effect on your posture while using your computer.

Be sure to optimize the position and orientation of your equipment by following the tips

outlined in "Arranging your work area"on page 2-1 so you can maintain a comfortable and

productive posture. Also, be sure to use the adjustment capabilities of your computer

components and office furniture to best suit your preferences now and as your preferences

change over time.

• Minor changes in posture can help avoid discomfort: The longer you sit and work with

your computer, the more important it is to observe your working posture. Avoid assuming

any one posture for an extended period of time. Periodically make minor modifications in

your posture to help deter any discomforts that might arise. Make use of any adjustments

that your office furniture or equipment provide to accommodate changes in posture.

• Short, periodic breaks help ensure healthy computing: Because computing is primarily a

static activity, it is particularly important to take short breaks from your work.

Periodically, stand up from your work area, stretch, walk for a drink of water, or otherwise

take a short break from using your computer. A short break from work gives your body a

welcome change in posture and helps to ensure you remain comfortable and productive

while you do work.

Chapter 2. 2-5

The regulation of Energy Star improves energy efficiency and reduces air pollution by

using more energy-efficient equipment in homes, offices and factories. One way to

achieve this goal is to use management to reduce energy consumption when products are

not in use. The default settings for monitors conform to Energy Star certification. Any

changes by users for more features and functionalities may increase power consumption,

which will exceed the limitation of Energy Star’s standard. If the user changes the options

related to energy efficiency when using, such as brightness, color mode, etc., select All

Reset Factory or choose the Energy Star option, the power consumption will be restored to

the energy efficiency with Energy Star standard.

For more information, please refer to (www.energystar.gov/products). All products of

Energy Star will be posted online and can be accessed directly by governments, public

institutions and consumers.
